The pop star has gone and got himself a rather dodgy hairstyle to match his rumoured girlfriend as the pair continue to act all loved up on holiday.

He shared a pic of him with CORNROWS on Instagram while posing with the blonde model who can be seen affectionately stroking his head, along with an older woman seen beaming at the camera.

Biebs captioned the snap: "Hailey made me get corn rows like an absolute douche bag, these will be off tomorrow trust me Danny."

The Sorry hitmaker appeared to confirm speculation he is dating the blonde model after posting a picture of them sharing a passionate embrace during a trip to St. Barts and though they don't want to "label" their relationship, they are very close.

A source said: "He loves Hailey as a friend and considers her one of his best friends.

"They both also have a strong attraction towards each other and this trip they have been having fun with their families, but also had some alone time.

"Hailey and Justin like to party and let loose and this romantic connection has always been there.
